Definitions
- This invention relates to a rasp-like instrument for forming a cavity in a bone and particularly a femoral rasp and a detachable extension end for preparing a cavity in the intermedullary passage of a femur for the implantation of a femoral stem prosthesis.
- prosthetic implants to replace natural joints of the body is well known.
- a femoral head is replaced by a prosthetic head connected to a prosthetic femoral stem.
- the implant stem is fitted into a cavity formed in the intermedullary passage of the femur.
- a rasp-like instrument is driven into the intermedullary passage to prepare the cavity for receiving the implant stem.
- the rasps are generally contoured to gross geometry of the implant stem to assure an accurate location and precise fit.
- Revisional implant stems are typically longer than the primary to provide secure foundations within the bone. Consequently, the rasp which forms the receiving cavity for the revision implant stem must also be longer than the rasp used in the primary procedures. Including additional rasps with varied lengths adds to the instrument count and costs to the hospital and manufacturer.
- the rasp of this invention eliminates the need for multiple rasps of various lengths to accommodate both the implantation of a primary implant and any subsequent revision.
- the rasp includes a detachable extension end which can be removed when the rasp is used to form the cavity for the primary implant stem and connected to provide a deeper cavity for the revision implant stem. Using a single rasp with a detachable extension end reduces the instrument count in the procedure thereby reducing costs to the hospital and manufacturer.
- an object of this invention is to provide for a novel and unique rasp-like reaming instrument for use in the preparation for implantation of a femoral implant stem prosthesis.
- Another object of this invention is to provide for an orthopedic rasp which can be used in the implantation procedures for both the primary implant and a revision implant.
- Another object of this invention is to provide for a rasp with a detachable extension end.
- FIG. 1 is a perspective view of the rasp of this invention showing the extension end connected to the rasp body.
- FIG. 2 is an exploded view of the rasp body.
- FIG. 3 is a perspective view of the extension end.
- FIG. 4 is a sectional view of the rasp body driven inside a medullary passage of a bone to form a cavity.
- FIG. 5 is a sectional view of the rasp body and connected extension end driven inside the medullary passage of a bone to form an extended cavity.
- FIGS. 1-3 show the rasp 10 of this invention.
- Rasp 10 includes an elongated tapered body 20 and detachable extension end 30.
- Rasp body 20 is substantially shaped to conform to the outer space of the implant stem which will be used.
- rasp body 20 has a proximal end 22 and a distal end 24.
- a mounting post 28 extends from proximal end 22.
- Mounting post 28 and indexed locating hole 29, which is of conventional design and well known in the art, is used to connect rasp 10 to a rasp handle (not shown) for driving the rasp into the bone.
- the mounting post and indexed locating hole also allow the rasp to be fitted with various provisionals and implant heads to determine the appropriate size and test the initial positioning of the implant stem.
- a threaded axial bore 25 is formed in the tip of distal end 24.
- Extension end 30 has an elongated configuration conforming substantially to the taper of rasp body 20.
- Extension end 30 has a concave connecting face 32 which mates with the convex face of distal end 24.
- a threaded post 34 extends axially from face 32 of extension end 30, which is threaded to mate with bore 25 in rasp body 20.
- both rasp body 20 and extension end 30 have a plurality of cutting teeth 14. Teeth 14 or similar structures commonly found in the art are used to shave portions of the bone tissue to form the implant cavity as the rasp is driven into the intermedullary passage of the femur.
- FIG. 4 shows the rasp used to form a cavity 3 in a femur 2 for a primary implant stem (not shown).
- FIG. 5 shows rasp 10 used to form a lengthened cavity 3 for a revision implant stem (not shown).
